iOS-simulator is not listed all the time. sometime its showing most of the time its not there. not doing any specific changes in my machine. Simply when i restart VS app. its missing.
tried unload & reload the ios project. still the same.
complete reinstall visual studio & xcode from scratch.
tried update xcode.
Nothing helped from above suggestions.
Would be really great help if someone could help me with this issue.
I've encountered the same problem several times and here are some of my suggestions:
Did you try switching to your Android project then switch back to iOS project? This should be the simplest way
In your iOS project options, create a build configuration specifically dedicated to iOS Simulators only. Make sure to set Linker behavior to Don't Link
Quit Xcode and Visual Studio first. Open Finder, press Command + Shift + G, paste the following path: Users/YourUserNameHere/Library/Developer/Devices/ You'll see a bunch of folders with encoded folder names and a file device_set.plist
Next delete all the folders in Devices directory, then open device_set.plist by double clicking it. This should open it in Xcode. You'll see a bunch of key-value pairs under DefaultDevices and DevicePairs, click on the arrow on the left side and delete of the devices listed there by hovering the mouse over a category and click the minus (-) button next to it.
Press Command + Shift + 2 to open Devices & Simulators Window (Alternatively you can choose on menu Window -> Devices and Simulators. Choose Simulators on the left sidebar. Delete all the simulators if there's still any of them showing up. Then create several simulators, ones that you really need for debugging your app. Quit Xcode, reboot the machine, open Visual Studio again.

I'm trying to build a cordova (version 4) based project with Xcode (for iOS). Everything is working until the process to validate the archive.
I'm build for iOS v > 7 and always have the error:
"iTunes Store operation failed: missing required icon file. The bundle does not contain an app icon for iPhone of exactly '120x120' pixels in .png format for iOS versions.
The thing is, there is such file, as shows in the printscreen!
printscreen with Xcode nav, with the Resources/icons folder
I'm sure the file icon-120.png is exactly 120x120px (I have saved several times it, using Photoshop, Fireworks, https://github.com/AlexDisler/cordova-icon plugin).
I don't know if I have to configure anything else. I have also reloaded Xcode, nothing seems to work by now :-/
go to Xcode, view -> Navigators -> Show Project Navigrator
Go to Resources in the project navigator
Click on Image-xcassets
you will see all the icons that the xcode is using to build. Most likely, you will a lot of warning sign attached to each icon. read the required size from each warning. right click -> go to finder, then change the icon size from preview app as required.
repeat for each icon with warning till you resolve all of them.
In xcode, I tried to add a tap gesture to my app and when I built it, it started a problem with Xcode. It goes from building, 'running on iPhone 6.1 simulator' to 'finished running on iPhone 6.1 simulator'.
If the simulator is closed, it starts up with a black screen and you cannot click the home button etc. If open, nothing happens, the app doesn't install but the simulator doesn't crash.
I have tried the armv6 architecture 'fix' but that didn't work. I have also cleaned the project and project data. I have reset the simulator multiple times as well.
If I add the old files to my new project, it works up to a point (I copy and paste old files into new) but then the same happens.
Thanks for your help in advance!
NOTE:
New blank projects build and run fine.
EDIT: It still didn't work after undoing my previous actions, and the simulator is responding according to Finder, although the screen stays black

UPDATE
I had a folder named 'resources' in my application, imported as a reference which, following links from the thread #arthan.v supplied me with fixed the problem. What I did was rename the folder to files and reimport it.
Thank you so much, I spent 2 days trying to fix it before now!
Click the Center Button in View on your right hand side of Xcode.
In your Bottom bar, you'll see error: failed to attach to process ID 0.
Check these error: failed to attach to process ID 0 and Xcode compiles my App, but can't run it in the simulator
This sometimes gets fixed by these steps:
iOS Simulator > Reset Content and Settings ... > Reset
Xcode > Build and Run
I experienced the same issue after I had re-organized some code and renamed the workspace and project. Eventually realized there was an old version of my test app on the simulator's homescreen. I delete that and then everything was building fine again.
You might need to add the device to the provisioning profile. I experienced this on Xcode 6 and a real device.
On Xcode when you build on device you can troubleshoot the app within the console. How can i do that with Titanium? It's very difficult without troubleshooting
What you can do is use the Ti.API.info('whatever') method to log everything you need and will help in debugging then while you run your app on the device and it is connected to your computer, just open xcode -> go to organizer -> click on your device -> and select console. Every Ti.API.info() log you do in your app will show up in the console.
Titanium's SDK (http://www.appcelerator.com/platform/titanium-sdk) is Eclipse with the Aptana plug-in. You can do the same debugging you'd do in Eclipse: set break points, step through code, set watch points, ...
To run your app in debug mode, start by setting some break points in your app. To do that right-click on the line number that's on the far left of our line of code and select "Toggle Breakpoint". Next, towards the top of the Project Explorer panel are several icons. One of them is debug. Click on that debug's dropdown menu and select the iphone emulator or ipad emulator. The app will compile for debug and run the emulator you chose. From this point on, everything is like debugging on Eclipse.
I am noobs at Xcode. I am on my second day of learning.
When I start Xcode, the main window has a button for "Getting Started with Xcode" and a subsequent link for "Xcode workflow tutorial"
Now I would simply like the help to be open at the same time as the IDE so that I can read and code. I clicked on the Xcode icon that opened up the original instance, but that doesn't seem to do anything.
How do I get both things to stay open at the same time?
Follow these steps -
Step 1: On opening X-Code, this window turns up-
Step 2: On clicking Getting started with Xcode , gives -
Step 3: On clicking Start Developing with Xcode gives-
Step 4: On clicking the link - Xcode Workflow tutorial present in Write a Sample Application gives-
Notice that in all the process your Xcode menubar remains unchanged i.e.,
Now, Click on File(or Cmd + Shift + N keyboard shortcut) , and select New Project should pop up the windows as shown in Workflow tutorial. Select the application type, saving should bring you new Xcode project. Arranging the two windows side by side should look some what like this -
Now code while you learn from the Workflow tutorial :)
Hope this is helpful.
You can open the documentation window via Cmd-Option-? and search for Getting Started with Xcode there. The option to open the documentation is also under the Help menu.
I generally open a project first and then open the documentation afterwards, if necessary.
I don't know why but now the default iphone simulator launched when I build the project is "ipad", but I want it to use iphone 3g instead.
Any way to set this preference?
On Mac, if you right click on the Simulator icon, you can select devices and it will open a new device.
Or go to File -> Open Simulator
In Xcode,
Click Product -> Destination -> iOS Simulator -> Choose Device to run.
Then build and execute Xcode project.
It works..
2022 Fix:
You have two options!
With the simulator running go to File > Open Simulator > iOS [current version] and select the desired device.
With the simulator running, right click the icon in the bottom toolbar, select Device > iOS [current version] and select the desired device
If you are using Expo, after selecting the new device will open in a new window, so you'll have both. Heres how to get Expo to run on the new device:
Close the device window you don't want (cmd + w)
You will now be able to "Run on iOS Simulator" and it will open up Expo Go on the new device.
2020 Fix:
With the simulator running go to File > Open Device > iOS > iPhone 11 and select the device. It will open up the device as another window but there won't be the Expo app.
Close the device window you don't want (cmd + w), then close the window with the device you would like.
Restart Expo (in the command window with it running do ctrl + c then re-run Expo with expo start
You will now be able to "Run on iOS Simulator" and it will open up with the selected device type.
In the chance that anyone reading this is building their app in react-native, the solution is the --simulator option.
For example:
$ react-native run-ios --simulator "iPhone X"
Go to Hardware > Device from simulator menu.
For me works changing active SDK from 3.2 to 4.0. If your project is mentioned to work on iPad and iPhone (or for compatibility matters) I believe the only way is manually switching active executable before running your app on simulator.
Apple:"iPhone OS 3.2 does not support iPhone and iPod touch devices. It runs only on iPad.".
You can select the device from the menu inthe simulator.
Try
Project > Active Executable , and select the one you want the most.
This worked for me. When I already have the app open on an iphone in "Simulator". I click File -> Open Simulator -> iOS 14.0 -> iPhone 8 (or iPad (7th generation))
None of the above worked for me, but the following took care of the issue :
Source:

Excerpt:
This works for Xcode 3.2.6. I don't yet use Xcode 4.x so don't know
if this will work for it or not. I would also quit Xcode before doing
this, just in case.
Go to the project folder and find the .xcodeproj file. Right-click
(or Control-click) it and select Show Package Contents. When the
package contents window appears, find the .pbxuser file (there might
be multiple such files if the project was worked on by multiple folks
and/or multiple computers). Open this file, which is XML, in your
preferred text editor. Find the section with the comment "/* Project
object */". There is most likely not a line in that section for the
key "activeSDKPreference". If there is no such key, add the
following:
activeSDKPreference = iphonesimulator4.2;
I found it after the "activeExecutable" key in that section, so I've
been adding it in that same order.
If there is already an "activeSDKPreference" entry, change it to
"iphonesimulator4.2".
Close the editor and the package contents window and then double click
the .xcodeproj file to reopen the project. Now you should have
entries for iPhone Simulator 4.2 and iPad Simulator 4.2 in the project
settings pull down menu, with iPhone Simulator 4.2 probably already
checked.
Additional Notes:
In my particular case, my entry in .pbxuser file had said
iphonesimulator4.3, even though under Project-Project Settings
menu
it said iphonesimulaor4.2!. However, once I changed it to
iphonesimulator4.2 in the .pbxuser file it stop auto selecting
iPad
all the time.
If you use SVN you will not see an "M" in SVN column showing that
you changed the project (even if you refresh/update). However,
just
do a "Commit Entire Project" and your changes to .pbxuser file
will
get updated. I also suggest referencing this post in your
check-in
comment in case you ever need to change it back for whatever
reason.
I finally solved this problem myself.
First, install new version of Xcode, which is Xcode 4.
Then set project scheme to iPhone Simulator and run app in Xcode several times.
And re-install Xcode 3 and the problem will be gone!
Yes, it's annoying. This worked for me:
Open the .plist file in group/folder resources and check the checkbox for key "Application requires iPhone environment".
If you are using Flutter, open the Runner.xcodeproj file in ios/ folder. Then right next to the Runner breadcrumb, you can click >and select what device to launch.
For Xcode Version 3.2.6 the following helps:
Project->Active Executable->iPhone Simulator 4.3
I don't know if it is working for newer Xcode environments.
Gary Tsui has also pointed out this approach previously.
